STM32H745是否支持TouchGFX？相关技术疑问咨询

Is STM32H745 unsupported by TouchGFX? #

No, this claim is incorrect. STM32H745 does support TouchGFX. The lack of direct search results likely stems from it being less commonly featured in official examples or community content, not from a lack of compatibility. The chip has the necessary hardware peripherals (such as LTDC, DMA2D) and sufficient RAM/Flash resources to run TouchGFX applications smoothly.

How to check TouchGFX support for an STM32 chip #

• Use STM32CubeMX: When creating a project for your target MCU, navigate to the middleware section. If TouchGFX is listed as an available option, the chip supports it. You can also use the TouchGFX Generator tool within CubeMX to confirm compatibility.
• Refer to ST's official TouchGFX documentation: The compatibility criteria focus on hardware requirements—specifically, the presence of display controllers (like LTDC), graphics acceleration (DMA2D), and adequate memory (Flash/RAM) to handle GUI assets and runtime operations. Any STM32 chip meeting these specs will support TouchGFX.

Why STM32H750 is widely used in TouchGFX examples and tutorials #

• Cost-performance balance: STM32H750 is a cost-effective member of the H7 series, offering enough RAM (up to 1MB SRAM) and Flash (up to 1MB) to run TouchGFX without overprovisioning, making it accessible for both prototyping and production.
• Reference board availability: The STM32H750VB Discovery kit comes preloaded with TouchGFX examples and includes a built-in touchscreen, which simplifies setup for beginners and tutorial creators.
• Widespread adoption: Its popularity in the community means more shared resources, troubleshooting guides, and pre-built projects, making it a go-to choice for demonstrating TouchGFX capabilities.
